How to turn off Speedstep?

Is there any way in Vista (32 bit) to turn off Intel’s Speedstep throttling?

Having spend a couple of hours going through Vista’s various and numerous
options (power options and so on) as well as spending some time researching
this on the net, I simply cannot find a way to turn speedstep off via the GUI.

My BIOS gives me two options: “Off� which sure enough turns speedstep off,
but sets the processors to run at minimum speed (1GHz), or “Enabled� which,
well, enables speedstep.

This used to be so easy in XP to turn off that I wonder why in Billy The
Gates’ name it seems an impossibility under Vista. The mind boggles … or am I
missing something here?

All advice & help would be much appreciated.

Relevant system info: Dell Precision M90, latest BIOS & drivers, Core2Duo
T7400

akita,

I don't know whether the following comments are helpful to you, but I found
it on another forum and thought I'd pass it on:

Use Vista's throttling. I had to live without Speedswitch when I switched to
Vista (I'm back on XP now) simply because of the incompatibility that
everyone here has. NHC bluescreens and CrystalCPUID doesn't work at all.

Use the advanced power schemes in vista and run the CPU throttling at 50%
(it'll clock itself down to the speedstep value, not the throttling). The the
dumbest trick of all to get the throttling working (took me a week to figure
this out ) put your computer into standby, and bring it back out, and your
processor is now throttled. Changing the throttling in the power management
can now change the speed on-the-fly too. However it can clock itself up to
the full speed of the processor, speedstep on or not.

From what I saw in the Internet, this speedstep is difficult or impossible
to turn off. I'll look around some more. I've nothing better to do. A
vendor is selling a utility called SpeedswitchXP, for managing the speedstep
thing, but apparently no Vista version is yet available, if it ever will be.

akita,

I found the following comment made in response to a question similar to yours:

you should switch your Vista's power plan to this one: You'll also need to
go into advanced power plan settings and make sure that both "min" and "max"
CPU states are set to 100%.

I've concluded that manufactures of computers have made if hard to turn off
speedstep so that users are forced to conserve power, thus also conserving
battery life on laptops. Is any of this useful?

I was having a speed step issue on my Dell laptop. The AC charger is no
longer identifying itself to the computer... it's probably a broken
1-Wire DS2501 id chip as described in
http://www.laptop-junction.com/toast...r-id-chip-died
....

Anyway, my laptop was running like crap, so I tried turning up the
minimums to 100% on Vista, but it didn't seem to help. I tried
installing RMClock and it reported that the cpu was running at 0.8Ghz
instead of 1.4Ghz (T5270). I tried using the high performance settings
on RMClock, but it didn't seem to help. Anyway, I checked out the BIOS
and noticed that in the info section it said:
Maximum CPU Frequency: 1.4Ghz
Minimum CPU Frequency: 1.2Ghz
Current CPU Frequency: 1.05Ghz
...so clearly something was still off.

Anyway, I ignored the 'defaults to minimum' warning and turned off
speedstep in the bios. When I turned Vista and RMClock back on, it now
reports 1.40Ghz and everything is running smoothly again.
